Title: Forming therapeutic atmos. with sodium chloride crystals - by grinding for entrainment in rising hot air stream
Inventor: TOROCHTIN MICHAIL DMITRIEVIC
IPC: A61M11/00
Filed: 1990-02-09
Abstract: After drying to a max. 20% moisture content, medium dispersivity NaCl crystals down to at least 20 microns are entrained by a stream of air extracted from the atmos. and heated to about 600 deg.C. The particles during ascent through a series of sepn. elements (5), formed esp. as rows of superimposed meshes (22) of dielectric material offset in a horizontal plane, and at a temp. below the NaCl melting pt., are converted into a high dispersivity aerosol, with 80-90% of the particulates smaller than 20 microns, at a concn. of 3.5-20  mg/cu.m of atmos. The air stream taking the aerosol for discharge from the appts.  head moves at 20-100 m/s., and the particles become negatively charged. The air column (3) height is 5-6 times the larger side of its rectangular cross-section. USE/ADVANTAGE - Esp. for bronchial asthma treatment. Final atmos. is comparable with that produced in natural salt treatment mines.

Title: Testing complex computer programs for technological processing - using projection of interrupt commands into sub-programs for safe interruption only in diagnostic mode
Inventor: SCHOEBEL ECKHARD
IPC: G06F11/36
Filed: 1990-07-12
Abstract: The method tests complex computer programs for technological processes with several subprograms running in parallel in real time by interruption of the subprograms for monitoring purposes. Interrupt commands are projected into the subprograms which do not cause interrupts during normal operation of the complex program. In diagnosis mode the interrupt commands activate the next interrupt command of one or more subprograms of a diagnosis programme which suspends the processing of each subprogram at locations not harmful to the technological process. USE/ADVANTAGE - For stepwise, simple running of complex programs without allowing unforeseen dangers to occur during interrupts.

Title: Jitter compensation for radar, satellite, communications systems, etc. - using duplicated memory cells and selecting stable values for input signal compensation
Inventor: HERRMANN FRANZ DIPL ING
IPC: G01D5/244
Filed: 1990-07-25
Abstract: A method of compensating jitter for the digital signals of a memory device address bus involves using pref. three memory cells, at least two of which have identical contents. When jitter occurs the stable value from the memory is processed instead of the varying original signal. Input signals are corrected using the stored values. The method involves setting address markers according to whether the measurement values fall within the value ranges of a memory cell.
Patent DE-4023913-A1 (DE)
Inventor: JUSUFBEGOVIC SUKRIJA
IPC: H05B7/085
Filed: 1990-07-27
Abstract: A stopper 1 is provided for obturating holes provided for receiving anode rods in anode blocks 3 used for the electrolytic extraction of base metals during the calcination treatment of the anode blocks. The proposed stopper 1 is notable for the fact that it is designed as a moulding of cellulose-containing material. This makes an exact-fit obturation of the anode holes 2 possible. Granular coke introduced as bulk material for the purpose of oxygen displacement between the anode blocks 3 arranged several at a time in the calcining furnace cannot penetrate the anode holes 2. Undesirable bonded material in the anode holes 2 and burn-out in the anode blocks 3 as a consequence of residual oxygen which cannot be completely avoided during the calcination process can no longer occur. The high strength of the stoppers 1 prevents the deformation of the holes 2 by anode blocks 3 arranged in the lower tier of the calcining furnace. At the end of the calcining process when the anode holes 2 have hardened, the cellulose-containing stoppers 1 are carburised and the carbon or ash remaining in the anode holes 2 can be sucked off without difficulty in a subsequent operational step.
